Description
Technical Field
[0001] The utility model relates to the technical field of packaged drinking water equipment, and more specifically, to a shrink film machine with condensation and heat energy recovery. Background Art
[0002] In the packaged drinking water industry, steam is commonly used to shrink the shrink film at the barrel mouth. However, traditional shrink film machines usually face the challenge of high energy consumption. Moreover, in the water replenishment link, these machines usually directly connect to normal temperature water. In winter, due to the low external temperature, the temperature of the connected water is also relatively low. The introduction of this low-temperature water will cause the temperature of the heating water tank to drop suddenly, which has an adverse effect on the steam output and the continuity of the output.
[0003] In addition, traditional shrink film machines also have the problem of steam overflow. Excessive steam overflow will not only cause waste of energy, but may also have an adverse effect on surrounding equipment, and even pose a safety hazard to the entire working environment.
[0004] Therefore, in view of these problems, the industry needs to seek more efficient and energy-saving solutions to ensure the stable operation of the shrink film machine and reduce the impact on the environment and the workplace. Summary of the Utility Model
[0005] The purpose of the utility model is: to solve the above technical problems, the utility model provides a shrink film machine with condensation and heat energy recovery.
[0006] The utility model specifically adopts the following technical solutions to achieve the above purpose:
[0007] A shrink film machine with condensation and heat energy recovery includes a frame, a hot water tank, a heating pipe, a film receiving channel, and a steam outlet; the shrink film machine further includes a heat energy recovery pipeline, which is fixedly installed on the inner top wall of the frame and located above the film receiving channel. One end of the heat energy recovery pipeline is provided with a normal temperature water inlet, and the other end passes through the frame and is arranged in the hot water tank. The film receiving channel is a prior art, and the utility model does not make specific elaboration. The hot water tank is fixedly installed on the top of the frame, and the heating pipe is arranged inside the hot water tank to heat the water in the hot water tank. The normal temperature water inlet is used to introduce normal temperature water.
[0008] One end of the steam outlet is communicated with the top of the hot water tank, and the other end passes downward through the hot water tank and enters the inside of the frame to be connected with the air inlet of the film receiving channel. The steam in the hot water tank enters the film receiving channel through the steam outlet.
[0009] The steam outlet is a pipe structure. A fixing sleeve is hermetically and fixedly sleeved on the outer wall of the hot water tank where the steam outlet is located. The fixing sleeve includes a limiting ring and a connecting sleeve formed integrally. The outer wall of the connecting sleeve is provided with threads, and the connecting sleeve is hermetically connected to the bottom of the heating tank by threads. By setting the fixing sleeve to fix the steam outlet, the connection between the steam outlet and the hot water tank is hermetically connected to prevent water leakage.
[0010] The heat recovery pipe is an S-shaped circulation structure. The S-shaped circulation structure makes the normal temperature water flow a long distance, and the S-shaped circulation structure has a large area, so the contact area with the steam per unit time is large, and the condensation and heat absorption effects are good.
[0011] A ball valve switch is provided at one end of the heat recovery pipe located in the hot water tank.
[0012] A shielding cover is provided on the outer wall of the frame. The shielding cover is arranged on the outer periphery of the film winding channel. The upper end of the shielding cover is connected to the top of the frame, and the lower end extends to the half position of the barreled water. By setting the shielding cover, steam overflow is avoided. In addition, the two side walls of the shielding cover in the moving direction of the barreled water are designed into an arch structure to facilitate the passage of the barreled water. The shielding cover can also be screwed to the film winding channel to fix it and make it more firm.
[0013] Working principle: A conveyor belt is provided below the film winding channel. The conveyor belt transports the barreled water. A shrink film is sleeved on the barrel mouth of the barreled water. The barreled water is transported to the film winding channel by the conveyor belt to heat and shrink the shrink film. The excess steam overflows from the film winding channel and accumulates above the frame, is condensed by the heat recovery pipe and heats the normal temperature water in the heat recovery pipe. After the hot water tank is heated, steam is generated and the water consumption decreases, the water level drops, and the ball valve switch is opened to allow the heated normal temperature water to enter the water tank for continuous heating.
[0014] The beneficial effects of the present utility model are as follows:
[0015] By setting the heat recovery pipe to condense the steam, steam overflow is avoided from affecting the working environment. At the same time, the heat energy absorbed by the heat recovery pipe can also preheat the normal temperature water, avoid the water temperature entering the hot water tank being too low, reduce energy consumption, and solve the problem of too low water replenishment temperature in winter.
